    games-fps/alephone: update live to avoid use of ffmpeg
    
    We can get mp3 support via media-libs/libsndfile and there's
    no currently-packaged scenario that relies on ffmpeg for
    video decoding.

    games-fps/alephone: add 20250302-r2
    
    This ebuild drops the dependency on ffmpeg as we don't require
    it for any currently-packaged functionality (media-libs/libsndfile
    can provide mp3 support).
